I have a Honda rancher FPE, 2012. Right front brake problems. When I press the break sometimes it goes all the way, I can pump it a little and i get brake again. I thought I needed to bleed the brakes, so I did, same problem. Changed the master cylinder. still the same problem. Let it set for a couple of weeks, no leaks. Can anyone think of something I might have missed ? Thanks.

 

You will get a good "pedal" when you get all the air out of the system provided the master cyl is OK and, as it is new, it should be. Quad brakes can be difficult to bleed. Regarded as bad practice but it works, I put a clamp on the hose behind the master cyl, try brake, lever should go solid, open LH bleed screw, release clamp and press lever down, refit clamp, let lever up, release clamp and repeat until all air is out of LH side, keep checking there is fluid in the reservoir. Do the same with RH bleed screw. You should then get a good "pedal." If the problem comes back but you are not loosing fluid, you must have a bad wheel bearing on the front and the disc is knocking the brake piston back as it slops about.

 

Thanks for the info.
